>if he messes with NATO then he will be finished
Nobody with thousands of nukes is finished until the nukes are launched or neutralized.
One does not simply launch thousands of nukes, and considering our state of nuclear readiness, I’m guessing that the Russians have an even more decrepit system. The use of nuclear weapons by civilized nations is akin to a Mexican Stand-off, the first to attack will lose. If the Russians didn’t launch during the Cold War, then they sure as hell wont now.
